Vlookup - Partial Match

Hello,

Im trying to do vlookup between 2 columns, i.e. If Column C Info (Partial Match) Is Not On Column A, then Display Result In Column F (where it wasn't a partial match), Else Leave Blank


If there is a partial match, display nothing.

Please see attached spreadsheet.

The formula I tried, in column I is obviously not giving desired result.
=IF(ISNA(VLOOKUP(C2,$A$2:$A$5,1,TRUE)),"-",(VLOOKUP(C2,$A$2:$A$5,1,TRUE)))
